Influence of mineral fertilizers and microfertilizers on potato yield

Abstract

The highest productivity of potatoes is ensured by the optimal balance of agrotechnical, physiological, and economic-organizational factors under any weather conditions. Fertilizers play an important role in shaping potato yields, but questions about their use in conditions of sharp climate change remain open. So, research on the influence of micronutrients on potato plants requires analysis of their interaction with plants at different levels and stages of application in cultivation technology. Thus, the application of mineral fertilizers and spraying potato plantations with preparations containing micronutrients determined the level of potato tuber yield for the Slovyanka variety. Increasing the background of plant mineral nutrition through the application of N30P30K30 provided a yield of 18.3 t/ha and an additional 2.0 t/ha of production or 12.3%, and with N45P45K45 – 20.6 t/ha, an additional 4.3 t/ha or 26.4 %, respectively. The treatment of plantations with microfertilizers contributed to an increase in potato yield on all backgrounds of mineral fertilization: without applying mineral fertilizers, the use of microfertilizers provided a yield at the level of 17.9 t/ha (Reakom Kartoplya) and 17.2 t/ha (Alpha Grow Kartoplya), and an additional 1.6 t/ha or 9.8 % and 0.9 t/ha or 5.5 % of tubers, respectively.
